Hi Willow, Welcome!
Be careful with the Zoloft, That's a real weight gainer there! I took it for like 6 months or so and boy am i sorry that i did! Not only did i gain weight while on it but i didn't even realize it was happening and now i am having withdrawal syndrome from it even tho i weaned off it. My right eye vision is very very dim and i think, i hope that it is the Zoloft that caused it and it will return once my system is restored back to normal again.
The exercise and healthier eating is all that i needed for my depression. It does wonders!
Good luck to you. I hope you make the right decision for YOU.
